Description

Product Description

External tooth lock washers have serrations around the outer diameter, which provide better holding power due to a greater surface area. They provide maximum torsional resistance and prevent loosening from vibration and/or corrosion. External tooth lock washers work best with large head screws such as: round, pan, binding, or washer head screws.
